第一个Spring Boot程序启动报错了（番外篇）
Spring Boot内嵌了一个容器，我可以不用吗？我能不能用外部的容器呢？
当然是可以的！
然后，下面代码在pom文件中一定要有哦！
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
然后，我就配置了，我本机已经安装好的tomcat7，来运行。
然后选择
选择项目
点击apply，点击OK。完成
启动tomcat，查看日志
